I saw this on my computer screen the other day, and I’ve got to say it really warmed my heart. I’ll explain below if it doesn’t provoke that reaction for you.

So here’s why that made me happy. Well for one, it was the first time Jacob had left stuff on my computer that I found later. And of course he left his name there.

But moreover, he’s learning a bit about the Unix shell. sl is a command that displays an animated steam locomotive. I taught him how to use the semicolon to combine commands. So he has realized that he can combine calls to sl with the semicolon to get a series of a LOT of steam trains all at once. And was very excited about this discovery.

Also he likes how error messages start with the word “bash”.
